" To detoilod .'eectonai view on the portion of the driving gear alongpropriete this side, the driven gear will be turning more slowly. Theremote driving and driven gears in Fig. l are numbered 57 and 58, andtheir construction is the same excepting that their high and low sidesare reversed from the position of the high and 10W sides of those in theforeground, the result being that the slow side o the driven ear 58 isdiametrica'lly opposite the slow side of the driven gear 56. The shafts22 of the driven gears carry cranksy 21 connected with the itman rods 23described above, and it will lie noted in Fig. 1 that the crank 21 ofthe gear 5G is at the beginning of the slow Side of this gear, or inother words substantially 900 in advance of the hi hest point of thisgear.

Vith this construction of driving mechthe nearer crank 21 in Fig. 1 isin position to start the active stroke of its pusher to the left, andthe slow side of its gear 5G is coming into mesh so that the foot 18with its toe 2l) in the earth, is about to move rearward at a relativelyslow speed to drive the tractor forward. T he shifting disk 24 is atrest and its pin in the slot 26 of the carrier keeps the foot in theearth. As the pusher completes its stroke, the cam 42 trips the detent40, the latch 29 engages the lower seat 3l in the disk 24, and thelatter is thus locked to its operating disk 28 and turns with it forhalf a revolution, until the latclr is tripped at the top and the detentagain holds the shifting disk 24. The intermittent rotary movement ofthe disk 24 thus produced is timed to synchronize with thereciprocations of the pusher, because both are driven throughconnections with the same main shaft At the conclusion of the slowactive stroke of the pusher the pin 25 rises, and the foot is thuslifted out of the ground during the rapid retractive stroke, andmeanwhile the other ioot (or others ii" there he more than two) are maleing their active and rctractive strokes in the same manner. l

What is claimed is:

l. A propelling apparatus having a prime mover, a reciprocatory pushermember, a shiftable guiding member for directing the pusher memberalternately in operative and inoperative paths and consisting of a diskhaving a sliding connection with the pusher member and means actuated bythe prime mover for operating said members in timed relation.

2. A propelling apparatus having a prime mover. a reciprocatory pushermember actuated by the prime mover, a shi'ltable guidini,r memberconsisting ot' a revoluble element having a pin and slot connection withthe pusher member and means for imparting an intermittent movement tothe revolu anism,

ble element to alternately dispose the pusher member in operative andinoperative paths.

3. A propelling apparatus having a prime. mover, a reciprocatorv pushermember actuated by the prime mover and transversely movable to occupyoperative and inoperative paths, a shiitable member consisting of a diskhaving a pin and slot guiding connection with the pusher member and acontinuously movable operating member actu ated by the prime mover andhaving pickaip mechanism l'or imparting intermittent advance movement tosaid disk.

4. A propellingr apparatus having a prime mover, a reeiprocatory pushermember actuated by the prime mover and transversely movable to occupyoperative and inoperative paths, a shiftable member consisting ol a diskhaving a pin and slot guiding connection with the pusher member and acon tinuously movable operating member ai tuated by the prime mover andhaving a latch for periodi 'ally engaging and alter nately disengagingsaid disk.

5. A propelling apparataus having a prime mover.y a reciprmatory pushermem ber actuated by the prime move and having a pivotal carrier elennntprovided with a pusher toot,y a shiftable member consisting ot' arevoluble disk having a pin and slot guiding connection with the pushermember and a continuously movable operating member actuated by the primemover and having a latch for periodically e raging and alternatelydisengaging said disk for imparting intermittent advance movementthereto.

(i. A propelling apparatus having a prime mover. a reciprocatory pushermember actuated by the prime mover and provided with a pivotal carrierelement having a pusher toot, a shil'table member consisting ot arevoluble disk having a pin and slot guiding connection with the pushermember, a delent for engaging and holding said shil'table member whenthe related pusher member is in its operative position`r a continuously| revoluble operating member actuated by the prime mover andhaving a latch for periodically engaging said shift able. member toimpart advance movement thereto, and trip mechanism for disengaging saidlatch from the shiftable member during the, active movement of thepusher member.

A propelling apparatus having a prime mover, a` reciproeatory pusher member actuated by the prime mover and transversely movable to occupyoperative and inoperative paths, a` shit'tahle member consisting of adisk having a guiding connection with the pusher' member, a yieldingdetent for locking the shiftahle member in a, fixed position during theactive movement of the pusher member, a continuously revolubleoperatingr member actuated by the prime mover and provided with meansfor periodically disengaging said detent from the shiftahle member, alatch carried by the operating member Jfor engagement with the shftablemember t impart intermittent forward movement to the latter, and a tripfor disengaging the latch at intermediate points in the path of movementof the operating member.

S. In a propelling apparatus, the eombination with a pusher mounted atone end for reciprocation, shifting mechanism ineluding two diskswhereof one is constantly rotated from a prime mover and the other isintermittently driven by the first, and a sliding` connection betweenthe driven disk and the pusher for guiding the latter during its activestroke and raisingjr it on its retraotive stroke; of drivingr mechanismactuated by the same prime mover, and connections between it and saidpusher for moving the same slowly 0n its active stroke and retraetiugirit more rapidly.

In testimony whereof I afiix my signature.
